Electrolysis and liquefaction of hydrogen requires much electric power. The vehicle needs about 8 times more electric power than a plug-in-hybrid of the same size.
|
| Hybrid vs hydrogen
|
|
|
The duell over the future of mobility. In one corner the since decades proclaimed hydrogen, on the other side of the ring: Hybrid with Lithium based batteries.

|
|
Facts on the subject hydrogen car. How realistic is an engine concept which distinguishes by low reach and expensive not available infrastructure?
|
| Hydrogen car: really the future?
|
|
|
Can this really be the future? Especially both tank solutions are not satisfyingly. With normal temperatures liquid fuel has many advantages.

| Section drawing: Opel Zafira fuel cell car
|
| 
|
|
|
On the 10,000 kms of marathon through Europe this cut car Opel Zafira is to be seen in the accompanying truck for press conferences also.
|
| Fuel cell in Opel Zafira
|
| 
|
|
|
200 fuel cells in series produce 125 to 200 volts. Top power 94 kW. The power density is 1.6 kW per liter or 0.94 kW per kg.
|
| Age of hydrogen
|
|
|
It becomes more and more plausible, that the prophets of the hydrogen age had been 2 places of the periodical system wrong. Not hydrogen but Lithium is the solution.
|
| Hydrogen age
|
|
|
Physics can not be changed. The physical physical of hydrogen are known. The hydrogen age is q question of believe.
|
| False investment hydrogen research for fuel cell cars
|
|
|
If all the billions for the hydrogen research would have been invested for better a lithium battery technology, we would already have hybrid cars to go 80% by electric power.
|
| 2,359 kWh per liter of liquid hydrogen
|
|
|
The tank is a main problem with the hydrogen. Hydrogen boils with -252,76 degrees Celsius and in a liter contains only 2359 Wh chemical energy.

| The hype about hydrogen

|
The author of our recommendet book Joseph J. Romm was advisor in the hydrogen and fuel-cells program during the term of office from President Clinton
|
| Opel Zafira consumption
|
| 
|
|
|
1.2 kgs of hydrogen on 100 kms in the European consumption cycle. However, hydrogen is very full energy with 33.3 kWh per kg. There are about 40 kWh on 100 kms.

| Test car fuel cells Opel Zafira
|
| 
|
|
|
With the 10000 kms marathon are 2 fuel cell cars. While the real marathon car is underway towards Turin, the second is available for test runs.
|
| Test drive Opel Zafira hydrogen fuel cell car
|
| 
|
|
|
Only gas pedal and brake. No gearshift but only push buttons for Forward, Backward and parkings. Thus it is a matter of disusing the left foot for the test run for the first time.
|
| Start from Salzburg toward Turin
|
| 
|
|
|
The next stage to Turin goes more than about 730 kms. While today's diesel cars of this size have loosely 1300 kms of reach, here it goes only with tank stop.

| Railway station Salzburg: stage of the hydrogen Zafira
|
| 
|
|
|
On the 2nd of June, 2004 the fuel cells Opel Zafira marathon stops in Salzburg. About 60% of 10,000 kms of tour of Hammerfest to Lisbon have already gone.

Where otherwise the engine is, is the fuel cell and about that point the voltage converter. It converts the delivered electric power to a higher voltage for the electric motor .
